A Batsman makes a score of 87 runs in the 17th inning and thus increases his average by 3. Find his average after 17th inning.

  • 140
  • 239
  • 352
  • 455
Answer:- 1
Explanation:-

Solution:
Let the average after 17th innings = x.
Then average after 16th innings = (x-3).
Therefore 16*(x-3) + 87 = 17x.
Therefore x = 39.
